Example one
As shown in fig. 1 and 2, the carrier for molding plastic parts includes a first supporting portion 110 and a second supporting portion (not shown in the drawings), a workpiece is located between the first supporting portion 110 and the second supporting portion, the first supporting portion 110 is rotatably connected to two lugs 111, each of the two lugs 111 is provided with a plurality of plungers 1111, the plungers 1111 are assembly parts of the carrier for molding plastic parts, the plungers 1111 are fixed to the lugs 111 through jackscrews 1112, the two lugs 111 can rotate around a rotating shaft 112 installed on the first supporting portion 110, and the plungers 1111 on the lugs 111 are rotated to be placed above the second supporting portion on the first supporting portion 110, all the plungers 1111 can be pressed against a side of the second supporting portion far away from the first supporting portion 110, and a cavity is formed between the first supporting portion 110 and the second supporting portion. The plastic part forming carrier circularly flows in the assembly line, and the plastic part forming carrier is subjected to injection molding and blanking processes in each circulation, so that the first bearing part 110 and the second bearing part need to be disassembled and assembled in one circulation, namely before the plastic part forming carrier performs plastic part forming operation or after the plastic part forming operation is completed, the first bearing part 110 and the second bearing part are disassembled into two independent bodies and simultaneously flow along the assembly line, in the plastic part forming operation process, the first bearing part 110 and the second bearing part are assembled together, so that the jackscrew 1112 is possibly loosened, and the position of the plunger 1111 is possibly changed, therefore, the position of the plunger 1111 on the lug 111 needs to be detected, so that all the plungers 1111 can be pressed on one side of the second bearing part far away from the first bearing part 110 in the plastic part forming operation.
In the prior art, the mounting positions of all the plungers 1111 on the lugs 111 of all the plastic part molding carriers are generally consistent during assembly by default, and the positions of the plungers 1111 on the first bearing part 110 after the plastic part molding operation is completed are detected by taking the mounting positions as standard positions, but because the second bearing parts of different plastic part molding carriers have processing errors during processing, the mounting positions of the plungers 1111 on the first bearing parts 110 of different plastic part molding carriers are different during actual assembly, so that the detection method cannot accurately judge whether the positions of the plungers 1111 on the first bearing parts 110 are qualified, and further cannot accurately judge whether the plastic part molding carriers are qualified.
In order to solve the above problems, the present embodiment provides a method for detecting a plastic molding carrier, referring to fig. 3, the method for detecting a plastic molding carrier includes:
s1, acquiring and recording a first assembly parameter of an assembly part on a plastic part molding carrier to be used for molding a plastic part, and binding the plastic part molding carrier and the first assembly parameter;
s2, obtaining a second assembly parameter of an assembly part on the plastic part forming carrier for forming a good plastic part after the plastic part forming carrier completes the plastic part forming operation;
and S3, comparing the deviation of the second assembly parameter and the first assembly parameter of the same plastic part molding carrier, and correcting the deviation if the deviation exceeds a preset deviation range.
In this embodiment, before any plastic part forming carrier performs plastic part forming operation, the position parameter of the plunger 1111 on the first bearing portion 110 is obtained, and is taken as the first assembly parameter, and after any plastic part forming carrier completes plastic part forming operation, the position parameter of the plunger 1111 on the first bearing portion 110 is obtained, and is taken as the second assembly parameter, that is, the standard position of the plunger 1111 is not set in this embodiment, but the first assembly parameter of the plunger 1111 on the first bearing portion 110 before any plastic part forming carrier performs plastic part forming operation is compared with the second assembly parameter of the plunger 1111 on the first bearing portion 110 obtained after the plastic part forming operation is completed, so as to accurately determine whether the position parameter of the plunger 1111 on the plastic part forming carrier is qualified.
Specifically, when the deviation between the second assembly parameter and the first assembly parameter of the plunger 1111 exceeds a preset range, it is determined that the position of the plunger 1111 on the first bearing part 110 is not qualified, and when the deviation of the position of the plunger 1111 is within the preset range, it is determined that the position of the plunger 1111 on the first bearing part 110 is qualified.
In combination with the above, the plunger 1111 of the first bearing portion 110 in the present embodiment is a fastener of a plastic molding carrier, and is also the above-mentioned assembly. Of course, in other alternative embodiments, the assembling member may also be an insert or a positioning member of the plastic molding carrier, which is not specifically limited in this embodiment.
It can be understood that, in this embodiment, the first bearing part 110 and the second bearing part are in a separated state before the plastic part forming operation and after the plastic part forming operation is completed, that is, the first bearing part 110 and the second bearing part respectively flow along the assembly line, in this embodiment, only one detection station needs to be arranged along the assembly line, the detection station is arranged at the front end of an injection station for injection molding on the assembly line, after the detection of the first bearing part 110 at the detection station is completed, if the position of the plunger 1111 on the first bearing part 110 is qualified, the first bearing part 110 and the second bearing part flow to the injection station for assembly and injection molding, and after the plastic part forming operation is completed, the first bearing part 110 and the second bearing part flow to the detection station along the assembly line in a circulating manner. That is, in the present embodiment, the position parameter of the plunger 1111 on the first bearing part 110 acquired by the current detection is the second assembly parameter compared to the position parameter of the plunger 1111 on the first bearing part 110 acquired by the previous detection, and is the first assembly parameter compared to the position parameter of the plunger 1111 on the first bearing part 110 acquired by the next detection.
Referring to fig. 1 and 2, in the present embodiment, the position parameter of the plunger 1111 of the first carrying part 110 is the distance between the plunger 1111 of the hanging lug 111 and the first carrying part 110.
Further, the step S3 includes:
and S31, comparing the deviation between the second assembly parameter and the first assembly parameter before and after the same plastic part molding carrier completes one plastic part molding operation.
In this embodiment, the plastic part forming carrier circulates in the assembly line, and in order to ensure that all the plungers 1111 can be pressed against the side of the second bearing portion far from the first bearing portion 110 in each plastic part forming operation, the present embodiment detects the position parameters of the plungers 1111 on the first bearing portion 110 of the plastic part forming carrier after each plastic part forming operation is completed.
Further, in order to obtain the information of the distance between the plunger 1111 on the hanging lug 111 of the first carrying part 110 and the first carrying part 110, in this embodiment, an appearance image of the plastic molding carrier needs to be obtained, in order to obtain the appearance image of the first carrying part 110 and analyze the obtained appearance image of the first carrying part 110, the embodiment further provides a detection apparatus, the detection apparatus comprises a detection unit and a control unit, as shown in fig. 4 to 6, the detection unit comprises a visual detection mechanism 210 and a moving mechanism 220, the visual detection mechanism 210 comprises a camera 211, the camera 211 is configured to obtain the appearance image of the plastic molding carrier flowing on the production line, the moving mechanism 220 comprises a horizontal moving component 221, the horizontal moving component 221 is configured to move the camera 211 so as to align the camera 211 with the plastic molding carrier, the control unit comprises a computer control mechanism (not shown in the figure), the computer control mechanism is in communication with the vision inspection mechanism 210.

It can be understood that, since a cavity is formed between the first bearing part 110 and the second bearing part in this embodiment, when the first bearing part 110 and the second bearing part are assembled together, the surface of the side opposite to the first bearing part 110 and the second bearing part is a cavity wall of the cavity, after the plastic part molding operation, the surface of the side opposite to the first bearing part 110 and the second bearing part may be abraded by scratches and the like, and when the abrasion degree is large, the produced workpiece may be flawed, thereby improving the product rejection rate and reducing the product production efficiency. In this embodiment, when the first bearing part 110 and the second bearing part are flowing along the flow line, the opposite sides of the first bearing part 110 and the second bearing part face upward, and the camera 211 can acquire the appearance image of the upward side of the first bearing part 110 and the appearance image of the upward side of the second bearing part, so that the embodiment can detect the wear degree of the surface of the opposite side of the first bearing part 110 and the second bearing part, and when the wear degree of the surface of the opposite side of the first bearing part 110 and/or the second bearing part exceeds the preset range, it is determined that the first bearing part 110 and/or the second bearing part is unqualified, thereby preventing the produced workpiece from being flawed, further reducing the product rejection rate, and improving the product production efficiency.

Referring to fig. 4, the vision inspection mechanism 210 in this embodiment includes more than two cameras 211 arranged along the conveying direction of the assembly line, and the two cameras 211 respectively acquire images of the first carrying portion 110 and the second carrying portion of the same plastic molding carrier, so as to improve the inspection efficiency and further improve the production efficiency of the product.
Further, the moving mechanism 220 in this embodiment further includes a vertical moving assembly 222, and the vertical moving assembly 222 is configured to move the camera 211 along the vertical direction to adjust the distance between the camera 211 and the plastic molding carrier, so as to ensure that images in the field of view of the lens collected by the camera 211 are clear, that is, the camera 211 can collect clear images of the first bearing part 110 and the second bearing part, so that the detection precision is improved, and the detection accuracy is further ensured.
As shown in fig. 6, in the embodiment, the moving mechanism 220 further includes a position detecting component 223, the position detecting component 223 includes a groove-type photoelectric switch 2231 and a light shielding sheet 2232 that can be placed in a detecting groove of the groove-type photoelectric switch 2231, the light shielding sheet 2232 and the groove-type photoelectric switch 2231 are alternatively disposed on the camera 211 and the vertical moving component 222, so as to accurately adjust a distance between the camera 211 and the first bearing portion 110 or the second bearing portion, thereby accurately focusing, and further ensuring that the camera 211 can accurately collect clear images of the first bearing portion 110 and the second bearing portion.
After the computer control mechanism of this embodiment analyzes the images of the first bearing part 110 and the second bearing part, when the result is that the first bearing part 110 and/or the second bearing part is qualified, the first bearing part 110 and/or the second bearing part continues to flow along the assembly line, and when the result is that the first bearing part 110 and/or the second bearing part is unqualified, the first bearing part 110 and/or the second bearing part needs to be repaired to correct the deviation, because the molding carrier of the plastic part in this embodiment circulates in the assembly line, the control unit in this embodiment moves the first bearing part 110 and/or the second bearing part out of the assembly line, that is, the step S3 further includes:
and S32, moving the plastic part molding carrier out of the production line.

and S33, comparing the deviation between the second assembly parameter after the same plastic part forming carrier continuously completes more than two plastic part forming operations and the first assembly parameter before the first plastic part forming operation.
Since the position parameters of the plungers 1111 on the first supporting portion 110 of the plastic part forming carrier usually do not change significantly before and after the first plastic part forming operation, that is, the position parameters of the plungers 1111 on the first supporting portion 110 of the plastic part forming carrier usually change significantly after more than two plastic part forming operations, at this time, all the plungers 1111 cannot be pressed against the side of the second supporting portion away from the first supporting portion 110 at the same time in the plastic part forming operation. The present embodiment improves the production efficiency by reducing the number of detection times of the plastic molding carrier.
